Each section more particularly to heaters of the so-called cn'- contains headers Ill and II at opposite ends and in vector type.

Referring now to all the viewss' ultaneously, It will be noted that the frames l4 form what is the heater consists of a plurality of sections A almost a continuous duct through the vertical which may be connected in various combinations, nests of sections, thus confining the air as it flows upwards through the sections. These frames also form a part of the secondary heating surface, in that they absorb a certain amount of heat from the fins which might otherwise be dissipated, particularly where the heater is installed in a wall recess. Furthermore, the frames support the ends of the fins and prevents breakage.

While I have shown the sections as made up with one or two oval tubes, it is evident that more tubes may be'used and that the tubes might be other shapes than oval. It is also evident that the arrangement and staggering of the fins may be varied.

From the foregoing it will be seen that the present heater is of exceptionally strong and rugged construction and may be handled without danger of breakage; that it lends itself to any combination desirable; that it may be installed in any wall space or cabinet; and that the air passing through it is forced into intimate contact with all the heating'surfacesIboth primary or secondary.

.lHaving described my invention and its objects, which I claim as new and wish to protect by LettersPatent is:

g 1. A cast metal heater section of the convector. type comprising a horizontal tube having a header at each end; a rectangular frame,

' of substantially the same height as the section,

surrounding said tube and said headers; a set i of fins formed between the tube and headers and the sides of said frames and extending from the horizontal center axis of the section to the top of the section; another set of fins formed between the tube and headers and the sides of the frames but extending from the center axis to the bottom of the section; said sets of fins staggered in relation to each other; and openings in the top and'bottom of said headers for connecting the sections vertically above each other.

2. A cast metal heater section of the convector type comprising a horizontal tube having a head-er at each end; a rectangular frame, of

' substantially the same height as the section, surrounding said tube and said headers; a set of fins formed between the tube and headers and said frames and extending from the horizontal center axis of the section to the top of the section; another set of fins similarly formed between the tubes and between the tubes and the sides of the frames but extending from the cent-er axis to the bottom of the section; said sets of fins staggered in relation to each other; and openings in the top and bottom of said headers for connecting the sections vertically above each other.

4. A cast metal heater section of the convector type comprising a horizontal tube having a header at each end, a rectangular frame surrounding said tubes and said headers, a set of fins formed between the tubes and the headers and the sides ofv said frames and extending from the horizontal center axis of the section to the top of the section, another set of fins formed between the tube and headers and the side of the frames but extending from the center axis to the bottom of the section, said sets of fins staggered in relation to each other, openings in the top and bottom of said headers for connecting the sections vertically upon each other, and openings in the ends of the headers for connecting the sections horizontally.

5. A cast metal heater section of the con-..

vector type comprising a plurality of horizontal tubes having a common header at each end, a rectangular frame surrounding said tubes and said headers, a set of fins formed between the tubes and between the tubes and the sides of said frames and extending from the horizontal center axis of the section to the top of the section, another set of fins similarly formed between the tube and between the tubes and the side of the frames but extending from the center axis to the bottom of the section, said sets of fins staggered in relation to each other, openings in the top and bottom of said headers for connecting the sections vertically upon each other, and open ings in the ends of the headers for connecting the sections horizontally.
